furnace pipe passing through the bars into the room.

With my invention the bars are mounted in such a manner that those atdifferent parts of the register may be adjusted to different angles withrespect to each other and to the plane of the face of the register so asto direct the warm air passing therethrough in desired directions. Ifall of the bars are located in planes at right angles to the face of theregister all of the air is directed straight out from the register. Withmy invention the bars across the register may, at the central portion,be located at right angles to the plane of its face and at distancesaway from the center may be positioned at different angles so that theair passing through the register is caused to spread out or diverge, thedegree of spread depending upon the angle at which the register bars maybe positioned. It is also possible with my invention to cause the air toconverge and not spread outwardly from the register if such an effect isdesired. The adjustment of the bars is a matter of choice to obtain anindefinite number of effects in the manner in which the air passesthrough and from the register.

It is a primary object and purpose of the present invention to provide aregister of the character stated and one which can be manufacturedeconomically, which is durable in use and which serves the purposes fowhich it is designed in a very efficient manner. derstood from thefollowing description, taken in connection with the accompanyingdrawings, in which,

Fig. 3 is a fragmentary longitudinal section substantially on the planeof line 3-3 of Fig. 1.

Figs. 4 and 5 are sections on the planes of lines id and 55 respectivelyof Fig. 2, all sections being taken looking in the directions indicatedby the arrows.

Fig. 6 is a fragmentary section similar to Fig. 3 indicating the meansused to adjust the register bars to different angular positions.

Fig. 7 is a fragmentary section similar to Fig. 2 showing the adjustingtool in edge view.

Fig. 8 is a fragmentary section on a plane like The invention may beun-' that shown in Fig. 3 showing a modification in structure of theregister.

Fig. 9 is a fragmentary elevation of the locating bar for the registerbars in the form of structure shown in Fig. 8, and

Fig. 10 is a fragmentary section through one side of the modified formof register, the section being similar to that shown in Fig. 2.

Like reference characters refer to like parts in the different figuresof the drawings.

The open register frame is of rectangular form and has sides and endspressed or otherwise formed from fiat metal into angular shape in crosssection providing an outer face I with inturned legs or flanges 2disposed at right angles to the 15 face i and at the inner edges of saidparts I. The frame is reinforced by Z-bars having a flange3 spot weldedto the rear side of the face members I, a web 4 paralleling the inwardlyextending legs 2 and a flange 5 extending from the inner edge of 20 theweb 4 to said legs 2 as shown in Figs. 2 and3.

A plurality of elongated fiat register bars 6 are 10- cated between theupper and lower sides of the frame and at their outer edges haveextending pintles I passing through suitable openings in 25 the upperand lower flanges 2 of the frame whereby the register bars 6 are spacedfrom each other and pivotally mounted for adjustment to differentangular positions. At one end (see Fig. 2) a part of each bar .6 is cutaway to provide a projection 30 8 adjacent the inner edge of each bar. a

The bars 6 are joined together in separated. banks by connecting bars 9which have openings to receive the projections 8 on a selected number ofthe bars 6. For example, in Fig. 3, six of the 35 bars 6 are shown asconnected with a single connection bar 9. In this manner the wholenumber of bars 6 from one end to the other of the register are dividedin banks, the bars in each bank being connected together so that all ofthe same are ad- 40 justable simultaneously to the same angle. To holdthe plurality or bank of bars 6, which are thus connected together bythe bar 9, a clip In of the form shown in Figs. 4 and 5 is located so asto bear against two adjacent pintles I at one end 45 of the bars 6 andis clamped against said pintles by means of a screw II which passesthrough the face i and threads through the clamping member H3 (Figs. 2and 5) thereby providing a releasable clamp for holding a bank of thebars in any angular position to which adjusted. There will be one ofthese clamping clips for each of the banks of bars described. It is, ofcourse, to be understood that the number of the register bars 6 whichare joined together in a bank may be varied in the same register or thatit is not at all essential that six of the bars shall be joined togetherin any register but a greater or less number can be thus joined asappears best.

With this construction the several banks of bars may be adjusted todifferent angular positions and each bank of bars may have a differentangular position than any of the others. I have provided a suitable toolfor adjusting any of the banks of bars to a selected angular position,as shown in Figs. 6 and 7. prises an arc-shaped plate I2 having a rightangle bent flange l3 which may rest against afra'me' l. The arc-shapedmember 12 of the tool carries an indicating scale M which is a scale ofdegrees.- A handle I5 is pivotally mounted on a pivot pin- H5 at thecenter of the arc-shapedplate l2 and has a projecting lower end slottedat I [in which a slot at the upper edge portion of a bar fi-is adaptedto be received. The handle i5 is provided with an opening i8 over theindicating scale l4 and with a pointer I9 which when it is moved to anyparticular indicating figure on the scale insures, that the bars 6 willbe adjusted to the angle indicated. Then after a bank of bars has beenadjusted to a particular position the screw H for the clamp associatedwith the particular bank is tightened and the bars are firmly heldagainst change of position. The bars at the middle portion of theregister may be adjusted so as to stand at right angles to the plane ofthe face of the register. Those next to the middle banks might beadjusted to diverge therefrom oppositely at angles of 15, for example,and those still farther out adjusted to diverge at angles of 30; or anyother selectedangles of adjustment may be used. Likewise, the bars maybe adjusted outwardly from the middle sections so as to converge towardsaid sections as indicatedin-Fig. 3. The adjustment is a matter ofchoice and to obtain the best passage of air and the movement thereof ina direction which is desired.

In Figs. 8, 9 and 10 a modified form of structure is shown. The frame isthe same as in the previously described register structure and theregister bars 6 are the same substantially in all respects. Instead of anumber of the bars being joined together in a bank as previouslydescribed all of the bars 6 are connected with a single flat bar 20which lies alongside of one of the legs 2, andwhich has openings 2|through which all of the pintles 'l of the register bar 6 pass as shownin Fig. 10. The bars 6 in this form of structure are likewise cut awayat the end Where the bar 211 is located to provide projections 23 whichare seated in openings 22. in bar 28. These openings 22 may be locatedat any desired or selected positions in the length of the bar 20 so asto give The tool com 6'- at different places in the length of theregister may be provided by suitable location of the openings 22.

With the present invention a simple and very effective structure ofregister for controlling the direction of air passing through theregister is provided in a very simple practical and effective manner.The register of my invention has proven very successful in use. Theinvention is defined in the appended claims and is to be consideredcomprehensive of all forms of structure coming within their scope.

I claim:

1. A register comprising, an open frame having spaced apart parallelsides, each of said sides having spaced pivot receiving openingsthereinin the lengths of the sides, grille bars extending between saidsides of the frame, each of said bars at each end and adjacent one edgethereof having a projecting pivot passing through said openings in theopposite sides of the frame, each of said bars at one end having anintermediate portion removed to provide projections adjacent theopposite edges of said grille bars, and a connecting bar located at theinner side of and alongside one of said sides of the frame having pivotpin openings through which the pivots on said grille bars pass, saidpivot openings being located adjacent one edge of the connecting bar,said connecting bar adjacent its opposite edge having spaced openings inwhich the said projections on the grille bars are received.

2. A register comprising an open frame, a plurality of grille barslocated within the frame opening and each having two spaced apartprojections on one of its ends and a connecting bar located adjacent oneside of said frame and having pairs of openings corresponding in numberto said grille bars and each pair of openings receiving the said twoprojections at the end of each respective grille bar. 7

3. The elements in combination defined in claim 2 in which one of saidprojections on each grille bar is longer than the other and said side ofsaid frame is provided with openings into which the longer projectionsof said grille bars extend.
